呂庭娟python集合set字典dict統計字元數目37,241不同字元數1,251

file = open('金融常識.txt','r',encoding='utf-8')
reading = file.read()
file.close()
print('檔案字元characters數:', len(reading))
mySet = set(reading)#將串列轉成集合,稱她 mySet得到1251
myDict = dict()     #定義字典dict稱他為 myDict例如改成DoraSet
for j in mySet:
    myDict[j] = 0
for i in reading:
    myDict[i] += 1
for j in mySet:
    print(f"字元「{j}」出現{myDict[j]:,}次數")
print(f'字元數目{len(reading):,},不同字元數{len(mySet):,}')
#python和其他所有語言不同的特徵 f string格式化字串文字
print(f"呂庭娟統計左引號(出現次數{myDict['(']:,}")
print(f'呂庭娟統計右引號)出現次數{myDict[")"]:,}')
print(f'呂庭娟統計504每題四個選項至少有{504*4:,}')
